事件類型

範例

下列程式碼範例示範此成員的使用。 在此範例中,事件處理常式會報告事件發生次數 MouseUp 。 此報告可協助您瞭解事件發生的時間,並可協助您進行偵錯。 若要報告多個事件或經常發生的事件,請考慮將 取代 MessageBox.ShowConsole.WriteLine 為 或將訊息附加至多行 TextBox

若要執行範例程式碼,請將它貼到包含繼承自 ToolStripItem 之型別實例的專案,例如 ToolStripButtonToolStripMenuItem 。 然後命名 實例 ToolStripItem1 ,並確定事件處理常式與事件相關聯 MouseUp

private void ToolStripItem1_MouseUp(Object sender, MouseEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "Button", e.Button );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Clicks", e.Clicks );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "X", e.X );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Y", e.Y );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Delta", e.Delta );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Location", e.Location );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "MouseUp Event" );
}
Private Sub ToolStripItem1_MouseUp(sender as Object, e as MouseEventArgs) _ 
     Handles ToolStripItem1.MouseUp

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "Button", e.Button)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Clicks", e.Clicks)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "X", e.X)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Y", e.Y)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Delta", e.Delta)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Location", e.Location)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"MouseUp Event")

End Sub
